Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00056 | $0.00365 |
| Opus 5 | $0.00028 | $0.00182 |
| Sonnet 5 | $0.00011 | $0.00073 |
| Haiku 4.5 | $0.00006 | $0.00036 |
Grade A, and why
openapi-utilities scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Openapi utilities
Bearer token required (see the openapi-auth skill).
Exchange Rate — https://exchange.altravia.com
Single endpoint returning real-time currency exchange rates.
PDF — https://pdf.openapi.it
One endpoint: generate a PDF from a URL or an HTML string; JavaScript is rendered.
.it Domains — https://domains.altravia.com
Register and manage .it domains (availability, purchase, DNS/contacts management). Domain purchase is a paid, durable action — confirm with the user first.
AI (RAG) — https://ai.openapi.com
Managed Retrieval-Augmented Generation:
POST /rag— create a RAG;GET /rag,GET /rag/{id},DELETE /rag/{id}POST /rag/{id}/documents— upload text documents or images (metadata supported for filtered search);GET/DELETEto list/removePATCH /rag/{id}— start indexing- Query:
POST /rag-search(plain retrieval),POST /rag-search-with-answer(LLM answer),POST /rag-conversation(conversational)
Typical flow: create RAG → upload documents → index → query → delete when no longer needed.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openapi-utilities is a skill published in the GitHub repository openapi/openapi-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 365 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
